This main roll is provided with a moved without injury to the other parts. To

spur-gear D, meshing with a spur-pinion D, accomplish this and for other purposes readily apparent, the rock-shaft H is mounted in the frame beneath the main and supplementary rolls and arms II and a handle h are secured thereto. Pivoted at the outer end of each arm is a screw-threaded rod 7t (See Fig. 3.) The upper end of this red is passed slidingly through a horizontal pivot h at right .angles with the axis of the pivot, which is rotatably mounted in lugs on the frame Gnear the end which holdsthe supplementary roll. This pivot is perforated and slidingly admits the screw-threaded rod therethrough between the lugs on the frame. Upon this rod and in threaded connection therewith is a thumb-nut h and between the thumb-nut and the swinging frame a compressible helical tensionspring h is mounted on the rod 71 so as to loosely encircle the same. The lower end of the spring is in constant contact with the thumbn ut,by means of which it can be raised and lowered upon the rod as desired. The spring being mounted on the rod, as described, is between the thumb-nut and the swinging frame and raises the frame when the rod is raised. When the rod is lowered with the spring, the supplementary roll returns by force of gravity to its original position. With these appliances thus arranged a connection is furnished between the rock -shaft H- and the swinging frame G, whereby upon turning the rockshaft in one direction the swinging frame and supplementary roll are raised into operative connection with the heating-roll, and by turning it in the opposite direction the supplementary roll is permitted to swing out of connection with the heating-roll. The turning of the thumb-nut will raise or lower the spring upon the rod as desired to the position on the rod necessary to raise the supplementary roll the desired distance and hold it with a yielding tension in operative connection with the heating-roll and permit it to return when the rod is lowered. As will be readily seen, these springs permit the swinging frame and the supplementary roll to move against the tension of the springs while in their raised position, so as to admit between the rolls material of unequal thickness subj ectto a practically uniform tension supplied by the springs.

In the process of ironing it is desirable and economical to use an apron formed of a woven fabric, such as duck or the like, to carry the material to be ironed into contact with the he'atingroll and to protect it from being soiled by the supplementary roll. In order to provide for this, an endless apron I is used, of nearly the same width as the supplementary roll, made in the form of an endless belt and passed around the supplementary and idler rolls E and K. The idler-roll K is rotatably mounted in sliding blocks 70, so that the desired tension can be placed on the apron. In order to move the sliding blocks backwardly and forwardly on the swinging brackets, adjusting-screws L are provided and rotatably mounted in brackets or upright lugs opposite the supplementary roll at the free end of each of the swinging arms on the swinging frame and passed through the smooth perforation in the sliding blocks, one of which is between each pair of lugs. The

.inner end or stem of each adjusting-screw is spring, and turning it in the opposite direction causes it to move forward and decreases the tension of the spring, allowing the sliding block in which the idler-roll is mounted to move toward the supplementary roll in response to the tension of the endless apron. The springs thus mounted and held at a tension serve to yieldingly hold the sliding blocks in the desired position and keep the endless apron under proper tension.

In operation the heating-roll is first heated by igniting the gas or gasolene burner, and the operating-lever is moved to the position shown in Figs. 1 and 2,which action, through the rock-shaft and toggle-levers, throws the swinging frame, with its supplementary roll and endless apron, up into contact with the heating-roll. The material to be ironed is placed on the apron and the heating-roll r0- tated by means'of the crank-lever d, which, through the gearing D, D, D and D rotates the supplementary roll as well and carries the material into and between the heating and supplementary rolls. By raising the opcrating-lever h the toggle-levers are operinto and out of contact with the heating-roll,

substantially as described.

2. In a mangle of the class described, the combination of a main frame, a heating-roll rotatably mounted in the main frame, a swinging frame pivotally mounted on the main frame, a supplementary roll rotatably mounted at or near one end of the swinging frame, an

idler-roll mounted at or near the other end of the swinging frame, an endless apron passed around both of the last-named rolls, a rockshaft and toggle-levers connecting the rockshaft with the swinging frame whereby the movements of the rock-shaft operate such swinging frame, substantially as described.

3. In a mangle of the class described, the combination of a main frame, a heating-roll rotatably mounted in the main frame, a swinging frame pivotally mounted on the main frame, a supplementary roll rotatably mounted at or nearone end of the swinging frame, an idler-roll mounted at or near the other end of the swinging frame, an endless apron passed around both of the last-named rolls, a rockshaft and toggle-levers connecting the rockshaft with the swinging frame whereby the movements of the rock-shaft operate such swinging frame, tension-springs interposed between the toggle-levers and the swinging frame to yieldingly hold such frame and its supplementary roll against the main roll so as to permit the vibrations of the same when in operation, substantially as described.

4. In a mangle of the class described, the combination of a main frame, a heating-roll rotatably mounted in said frame, a swinging frame pivotally mounted on the main frame, a rock-shaft and toggle-lever mechanism for operating the swinging frame, a supplementary roll rotatably mounted in the swinging frame adjacent to the heating-roll, sliding bearing-blocks is mounted on the swinging frame, an idler-roller rotatably mounted in the sliding bearing-blocks, an endless apron passed around the idler and supplementary rolls, and screw and spring mechanisms for moving and holding the sliding blocks under ayielding tension, substantially as described.

5. In a mangle of the class described, the combination of a frame, heating mechanism mounted in' the frame, an endless apron, smoothing mechanism between the heating mechanism and the endless apron a swinging frame mounted in the main frame, an aproncarrying roll mounted on the swinging frame adjacent to and movable toward and from the smoothing mechanism, an idler-roll on which and the apron-carrying roll the endless apron travels, movable bearings carrying the idlerroll, tension-spring mechanism in operative connection with the movable bearings and idler-roll mounted therein and holding the endless apron under tension, means for moving the apron-carrying roll toward and away from the heating and smoothing mechanism, and means for rotating the apron-carrying roll whereby the endless apron is caused to move between the apron-carrying roll and the heating and smoothing mechanism, substantially as described.

6. In a machine of the class described, the combination of a frame, heating mechanism mounted in the frame, an endless apron, smoothing mechanism between the heating mechanism and the endless apron a swinging frame mounted in the main frame, an aproncarrying roll mounted on the swinging frame adjacent to and movable toward and from the heating and smoothing mechanism, an idlerroll mounted on the swinging frame upon which roll and the apron-carrying roll the endless apron travels, means for moving the apron-carrying roll toward and away from the heating and smoothing mechanism, and means for rotating the apron-carrying roll whereby the endless apron is caused to move between the apron carrying roll and the smoothing mechanism, substantially as described.
